Are you using OPOS (UnifiedPOS/UPOS)?
If you are using an application that is written to interface with the OPOS (OLE Point of
Sale) standard, then the TransAct Technologies OPOS driver will allow you to
communicate with most TransAct Technologies printers. The OPOS driver provides the
mechanisms to print in all of the print modes supported by the printer.
Note: The TransAct Technologies OPOS driver only supports Microsoft Windows
operating systems.
Note: If you are using a USB printer, you will also need to install the TransAct
Technologies Virtual Serial (TVS) driver.
Note: If you are using an Ethernet printer, UPOS can be configured to interact directly
with the printer. In this case, you do not need the VSerial Ethernet driver.
Do you want to print from a Windows application?
Microsoft supports a Windows Printing API for Windows applications. This interface is
intended to support typical Windows page printers, and has features such as begin
document, end document, and tray selection. While this is not an ideal environment for a
POS printer, there are cases where such functionality is required.
To support this environment TransAct Technologies provides a Windows print driver with
extensions for POS, which may be downloaded and installed for most TransAct
Technologies printers.
Please read the Ithaca Printer API documentation included with the driver. A POS
printer is not the same as a typical consumer printer and requires unique consideration
when using a Windows printer API interface.
